Don’t buy as return/exchange policy is not upheld my employees

I bought a children’s costume today at Constantia Village and the friendly assistant told me if it didn’t fit or my daughter didn’t like it I could exchange or get a credit note. I popped into Cavensish tonight to get a credit note and return it and the very unhelpful person on duty looked exasperated and told me she is “just a casual” and she will phone her manager. She did this with such a bad attitude and not once told the manager that it was a child’s costume. Sorry computer says NO was her answer.. R399 and now what???? Manager on phone didn’t even ask to speak to me. I am fully aware of adult swimwear but I was assured by Constantia Village store it wouldn’t be a problem or I wouldn’t have bought it. Have always supported Accessorize and kids swimwear is good quality and have never had an issue with an exchange before... pathetic experience..
